ATTORNEY L. M. LIPMAN Feb. 19, 1963 DOOR HINGE 2 Sheets-Sheet 2 J Filed Jan. 10, 1961 %7/4 ATTORNEY hate This invention relates to hinged closures and more specifically to novel hinge structures.

In one of its more specific aspects the invention is directed to novel hinge structures and also to such structures in combination with an element of a door and a supporting element especially when said elements are made of metal having relatively thin wall sections. Such elements are well known to the art because they have been in common use for some time and generally are made from formed sheet or hollow extruded metal, such as aluminum or the like. The primary object of this invention is the provision of relatively inexpensive and readily assemblable means with a support to provide a novel and inexpensive hinge structure which may readily and easily be coupled with a door or other swingable closure.

The foregoing as well as other objects and advantages of this invention will be readily apparent from the following description and drawings, wherein;

As shown in the drawings, there is a rectangular door frame of a building. The door frame includes a lintel element 10 at the upper end thereof and a sill element '11 at the lower end thereof, and spaced vertically disposed jambs 12 extending substantially the full length of the door frame and between the lintel l0 and sill l1. Secured to the jamb member 12 by screws 13 is a vertical support 14 which preferably is a single unitary element composed of metal such as aluminum or the like and is produced by extrusion, and then is cut for receiving hinge elements. As shown the support 14 comprises a pair of rail members 15 and 15 connected to each other through an elongated hollow partial cylinder or knuckle 17, all extending substantially the full length between the sill 11 and lintel iii. The partial cylinder or knuckle 17 which is integral with rails 15 and 16 has an internal circumference greater than half but less than a full cir- 'cumference of the virtual circle of which it is a part so that a narrow slot 18 extends the full length of said par tial cylindrical part or knuckle 17. The rail 15 has a plurality and as shown three spaced short teeth 19 extending the full length thereof and the rail 16 has a re- '3,$?7,53ll Patented Feb. 19, 1963 2 inforcing stop rail 20 integral therewith, at right angles thereto, and extending the full length thereof.

The partial cylinder or knuckle 17 is cut away in a plurality of places and as shown in three places, spaced from each other to provide three cut-outs 22.

Each of the cut-outs 22, three of which are shown in FIG. 1, and one of which is shown in FIGS. 5 and 6 has a nylon bushing 21 located at one end thereof. The bushings 21 may be composed of other good-wearing material. Each of said bushings 21 is a short hollow cylinder terminating at one end in a narrow flange. The bushings are disposed as shown in FIG. 5 with the cylinders thereof located in the knuckle l7 and making friction-tight fit therewith and with the flanges thereof located at the ends of the cut-outs and being of an outside di ameter corresponding approximately to that of knuckle 17. A set of hinging elements are assembled with said knuckle 17 at the cut-out portions 22 thereof for hingedly supporting a door or the like to the support 14. Referring to FIG. 8, each set of hinging elements, as Shown for example, embodies three elements 26, 27 and 28. Elements 26 and 27, each consists of a hinge plate 30 having a plurality of spaced openings 31 through the thickness thereof to accommodate locking nuts or screws 32, and having a rib 33 near one side thereof, integral therewith and extending at right angles thereto, with a narrow strip 25 of plate 34 together with rib 33 providing a locking strip and corner as shown. Integral with each rib 33 is a solid cylindrical knuckle 35 whose outside diameter is approximately the same as that of the knuckle 1.7.

The upper face of knuckle 35 of element 26 is in substantially the same plane as the corresponding faces of the plate 30 and rib 33 thereof; the lower end of the rib 33: thereof is partially cut away so that its width is considerably less than that of the remainder of rib 33; and the lower end of the knuckie 35 has a short and smaller diameter cylinder or pintle 37 integral therewith, disposed centrally thereof and extending downwardly therefrom, with the lower face of the pintle 37 being in approximately the same plane as the lower end of piate 3d and rib 33 thereof. The lower face of knuckle 35 of element 27 is in substantially the same plane as the corresponding faces of the plate 36) and rib 35 thereof; the upper end of rib 33 thereof is partially cut away so that its width is considerably less than that of the remainder of the rib; and the upper end of the knuckle 35 has a short and small diameter cylinder or pintle 355 integral therewith disposed centrally thereof and extending upwardly therefrom, with the upper face of pintle 33 being in approximately the same plane as the upper surface of the plate 30 thereof. in both the elements 26 and 27, a face of the rib 33 is preferably ap roximately tangential to the cylindrical knuckle 35'; and the depth of cut away of the ribs 33 thereof is approximateiy equal to the altitude of the pinties 37 and The element 28 is preferably shorter than either of said elements 26 or 27 although it may be the same length as or longer than either which may be of the same or different lengths.

The element 28 preferably consists of a plate as having opening 31 therein, rib 4i and knuckle 22 which, except for the length, are of the same dimensions as the corresponding parts of elements 26 and 27. The length of element 25 is as great as and preferably greater than the length of the pintles 37 and 38.

Said elements 26, 27 and 28 may be easily and readily produced. For example, by extrusion, a single element (not shown) may be produced and this element is a combination of elements 25, 27 and 23 without any cut outs at the ends thereof. Then this element is machined to provide the cut-out portions at each end thereof to provide the pintles 37 and 38 and the reduced rib-widths at the ends thereof, after which it is sheared transversely in two separate planes to provide the three elements 26, 27 and 28 as before described.

The elements 26, 27 and 28 may be readily assembled with the support 14 and a door 50 thereby to hingedly couple the door 50 with support 14. The door 50, as shown, has an elongated vertical member or door edge 51 comprising a pair of narrow elongated plates 52 spaced from each other, with each plate 52 having a very narrow strip or flange 54 integral therewith. Located inwardly from the strips 54, which extend toward each other, is an elongated door edge plate 56 integral with the plates 52. The elongated plate 56 has a plurality of threaded openings in predetermined spaced relationship to each other, and together with a portion of plate 52 and strip 54 provides a locking corner for the hinge elements 26, 27 and 23.

A simple method for hingedly coupling the door 50 with the support 14- is to first place and drive a bushing 21 at the upper and lower ends of each of the three cut-outs, thereby to frictionally secure a bushing 21 at each end of the knuckle 17 defining the ends of cut-outs or cut away sections 22. Then an element 26 is disposed in its proper location with respect to member 51 and is so positioned that its plate 3%) lies flat on the outer fiat face of 56, with its openings 31 in registry with the appropriate threaded openings in plate 56 and the rib 25 thereof located in the corner and bears against the inner faces of strip 54, plate 56 and the connecting portion of plate 52 to rigidly and firmly anchor the rib 25 in position. Now bolts 32 are inserted through openings 31 thereof and make threaded engagement with the threaded openings in registry therewith to lock element 26 in position on door 50. In this manner three elements 26 as shown are locked in position on plate 56 of door 50.

The door 50 with the three elements 26 secured thereto and rigidly coupled therewith is moved into position close to support 14 and the combination is so positioned that each of the three pintles 37 is located in a cut-out 22 as shown in dotted lines in FIG. 6. Then the combination is lowered whereupon each pintle 37 is inserted into a bushing 21 and the reduced portion of rib 33 extends along knuckle 17, and each element 26 rests upon a flange or bushing 21. The so supported door 50 which is disposed in its outwardly swing position is sufficiently supported by the pintles 37 in the bushings 21 to permit assembly of the other parts therewith.

Now an element 27 is so disposed that its plate. 30 lies flat against the outer flat face of plate 56, with the knuckle 35 and pintle 38 thereof disposed above the element 26 and in a-cut-out 22, with the pintle 33 as shown in dotted lines in FIG. 6 located below the upper bushing 21. The element 27 is now slid on the outer face of 56 to dispose element 27 in its proper location with respect to members 51 and 17 and is so positioned that the pintle 38 thereof is inserted into and located in the upper bushing 21 with the flange of said bushing bearing against the upper face of knuckle 35 thereof and the reduced portion of the rib 33 thereof extending along the knuckle 17; and its plate 30 lies fiat on the outer face of 56 with its openings 31 in registry with the appropriate threading openings in plate 56 and the rib 25 thereof located in the corner and bears against the inner faces of strip, 54, plate 56 and the connecting portion of plate 52 to rigidly and firmly anchor the rib 25 in position. Bolts 32 are now inserted through openings 31 thereof and make threaded engagement with the threaded openings in registry therewith to rigidly secure element 27 in position on door 50 thereby to maintain element 27 in the aforesaid position with the pintle 38 thereof maintained in bushing 21. In this manner, three elements 27 as shown are located in position on plate 56 of door 50 with the respective pintles 38 thereof located in the upper bushings 21. The door is now supported by three 4 sets of hinge elements with each set being elements 26 and 27.

If desired and in the preferable embodiment of this invention there is combined a hinging element 28 with each set of elements 26 and 27. The plate 40 thereof is located in the space between the plates 39 of elements 26 and 27, and is so positioned that its rib corresponding to ribs 25 is anchored in the corner in the same manner as ribs 25 and its opening 31 is in registry with a threaded opening in plate 56 and its knuckle 42 is located in the space be tween knuckles 35, with the parts of 42 being in alignment with the corresponding parts of binge members 26 and 27 so that the space between said parts are completely filled so that there is a snug fit between said elements 26, 27 and 42. A bolt 32 extends through said opening 31 thereof and makes threaded engagement with the threaded opening in 56 in registry therewith to firmly secure the element 28 to the door and to maintain element 28 in fixed position relative to elements 26 and 27 and knuckle 17. Thus, the elements 26, 27 and 28 are in supporting relation with respect to each other and while separate units appear to be a single unit and indeed so act to hingedly support the door 50 on the support 14. In this manner, three elements 42 as shown are locked in position.

While the specific embodiment of the present invention has been described in detail, the invention is not to be limited thereby, because the specific embodiment is given by way of illustration and not limitation, it being understood that various changes and modifications may be made within the spirit of the invention.
